affine load fails



About the affine package,  I can't seem to get anything to work.

(I'm running Maxima 5.9.3 / clisp. load (affine); succeeds if I answer n
to the question about compiling while loading.)

I tried some of the examples shown by ? affine e.g.
grobner_basis ([3*x^2+1, y*x]);
   => undefined function MUST-REPLACEP
set_up_dot_simplifications ([y.x + x.y], 3);
   => lot of questions then
  FUNCALL: argument (LAMBDA (N) (APPLY 'HILBERT N 'NIL)) is not a function
fast_linsolve ([x+y=1, x-y=1],[x,y]);
   => variable $POLY_VECTOR has no value

Does anyone know how affine is supposed to work?
